Abstract

The aim of this study was to determine the physicochemical composition, aroma profile, and sensory properties of wines produced from Voltis grape cultivar in the 2024 and 2025 vintages at the Jazbina experimental vineyard, Faculty of Agriculture, University of Zagreb. Basic physicochemical parameters were determined by FTIR spectroscopy, volatile compounds were analysed using the SPME-Arrow-GC/MS method, while the wines were evaluated sensorially using quantitative descriptive analysis. Pronounced differences in alcohol content were noted between the two vintages, whereas total acidity and pH showed considerably lower variability. Among the aroma compounds, β-damascenone, β-ionone, and ethyl esters were singled out due to their significant contribution to the aroma profile. The wine from 2024. exhibited a more pronounced floral character, whereas vegetal aromas were more intense in the Voltis wine from vintage 2025. The results indicate the need for further research to better define the effects of yield, grape maturity, and climatic conditions and to establish optimal viticultural and oenological practices for the production of Voltis wines.
